Bongo Zooplankton Data from the R/V TINRO, NOAA Bell M. Shimada, F/V Northwest Explorer and R/V CCGS Sir John Franklin during the 2022 International Year of the Salmon Pan-Pacific Winter High Seas Expedition

This data set contains the zooplankton data collected using paired bongo tows from the R/V TINRO, NOAA Bell M. Shimada, F/V Northwest Explorer and R/V CCGS Sir John Franklin from February 5 - April 17, 2022 in the North Pacific Ocean. The paired bongo nets (60 cm in diameter, 253 micron mesh size) were deployed to a depth of approximately 250 m and retrieved vertically at 1 m s-1. Collected data are used to offer insights in zooplankton community composition, density and distribution. After the bongo net deployment and recovery, the net was rinsed down into the cod end. Volume of sea water filtered was determined using flowmeters. This dataset includes samples that were preserved in formalin. These samples were enumerated and identified to the lowest taxonomic rank possible or practical. Abundance (individuals per cubic meter) was recorded by species, lifestage, sex and size (range).

本数据集涵盖2022年2月5日至4月17日于北太平洋海域采集的浮游动物（zooplankton）数据，采样载体包括廷罗号研究船（R/V TINRO）、NOAA贝尔·M·岛田号（NOAA Bell M. Shimada）、西北探险家号作业渔船（F/V Northwest Explorer）以及CCGS约翰·富兰克林爵士号研究船（R/V CCGS Sir John Franklin），采样方式为配对博网拖采（paired bongo tows）。
配对博网（bongo nets）直径为60厘米，网目尺寸253微米，作业时被下放至约250米水深，以1米每秒的速率垂直起网回收。所采集的数据旨在揭示浮游动物群落组成、密度与分布特征。
在完成博网下放与回收作业后，需将网体冲洗至拖网囊网（cod end）内，滤过海水的体积通过流量计（flowmeters）测得。本数据集包含经福尔马林（formalin）固定的样本，此类样本已完成计数，并被鉴定至可行的最低分类学阶元（taxonomic rank）。
丰度（abundance，单位：个/立方米）按物种、生活史阶段、性别及尺寸范围进行记录。
